best bot for sending one-on-one LinkedIn group messages?

Does anyone know of any bots that are good at sending one-on-one messages to LinkedIn group members? In particular, are any such bots good at staying within the unwritten rules that are likely to get LinkedIn accounts restricted? For example, a good bot should limit how many messages are sent per account per day, have time delays between messages, limit total daily page views per account, and many other things.

Any bot that doesn't take these types of things into account will just wind up getting accounts banned.

Yes, I am sure I could create my own bot, but I am wondering if there are any existing bots that I could buy? Frankly, I am more interested in purchasing the knowledge that someone has built into the bot about how to avoid getting accounts banned than the bot itself.

I view that the main purpose of a good bot is to be a tool that reduces the incident rate of banned accounts. A good bot will ensure you don't run afoul of LinkedIn's unwritten rules.
